1 a a plication filed'september 23, 1922." Serial No. 590,005.

To all whomiitmay 00mm: y Be it knownthat I, CHESTER-G.- Hown, a citizen of the United States, residing at New Kensington, in the county of Westmoreland, State of Pennsylvania, have invented. certain new and useful Improvements in Wash.- ing Machinesaof which the following is a specification. s f

This-invention is for an improvement in brush washing machines and relates. particularly' to a tension adjustment for the scrubbing roll of such machines. y

In;brush washingmachines,the clothes are held against a rapidly revolving 'brushby means of a scrubbing roll which is yieldably urged toward the? brush. For different kinds of clothes, it is; desirable to; be able to vary the tension of the scrubbing {rolls so that wherethick and tjhin pieces are bemg washed, some pieces will not be held too firmly against theb'ru'sh while others are not held sufficiently tight against the brush.

The present invention has for its principal object to provide a roll mounting and spring adjustment for the roll which is more simple and efficient than other devices for this purpose now in use.

The invention may be readily understood by reference to the accompanying drawings, in which:

Fig. 1 is a front elevation of a part of a brush washing machine embodying my invention;

vFig. 2 is an end elevation of the part of the machine shown in Fig. '1; j

F "g. 3 is a section'on line III-III of Fig. 2;

Fig. 4 is a section on line IV--IV of Fig. 2. i

In the drawings, 5 designates end frame plates of a brush Washing machine, and 6 is a power driven brush rotatably carried between said plates in bearing 7. On each of the end plates 5, near the top thereof, is a lug 5 from which a link 8 is pivotally suspended by means of a suitable bolt 9. A spring 9" is carried on the bolt between the link and a nut 9 on the bolt which urges the link against the lug. The lower end portion of each of the links 8 has a bearing 10 therein, forming journals for supporting the opposite ends of a roller carrying shaft 12.

allow. the shaft considerable freedom of movement therein, the construc ztion being shown in Fig. 4 from which it will be seen that the end .of the shaftpasses throughia h'olewhich, islargerat its endsthan at its center, sothat the-shaft may assume differentyangular' positions a in the link. Loosely carried 'onutheshaft 12 is a scrubbing roller 11. Cotterpins 13 hold theshaft against endwise movement. a M ;Thesprings 9 preventthe roller from bumping or, jumping toward and away from the brush and from chatteringwhen. an

article is being washed between the brush andthe roller. have found that without thesprings,thescrubbing action is far in- 'feriorfandi that they are practically essentialE-for the operationof the ;Ib-1-ush;washer.

The links arepreferably of suflicient length slighly belowthat of thebrush.

. Formed in the links, intermediate the ends thereof, are a plurality of recesses or notches 14. Mounted on each link is a tensioning member 15 having a slot 16 therein through which the link passes. At one end of the member 15 is a handle portion or grip 17, and a finger hole 18 may be provided. Connected to the other end of each member 15 is one end of a coil tension spring 19, the other ends of the springs be- .to cause the Center: line of the roller to. be

mg secured to lugs 20 in their respective plates 5.

The springs exert a pull on members 15 to yieldably urge the links, and consequently roller 11, against the rotary brush. By adjusting members 15 to cause the metal at the end of slot 16 to enter one of the recesses or notches 14 in the links, the members 15 may be adjustably retained in position. When the members 15 are near the lower end of links 8, the scrubbing roller 11 is held more tightly against the brush than when the members 15 are at the upper ends of the links, due to greater tension of the springs when members 15 are near the lower ends and the increased leverage through which 1 they exert their pull.

To change the pressure of the roll against the brush, the operator grasps the two members 15 and pulls toward him until the ends of slot 16 dlsengage the notches or recesses 14. The operator then moves members 15 a up or down on the link, and lets them engage suitable notches 14 when he gets them to the desired position. In this way, the

roll pivotally connected with said frame formovably supporting the scrubbing roll,

- springs secured to the frame at each end of the brush, and means on said links' movable longitudinally thereof, to which said springs connect, to yieldably hold the scrubbing roll against the brush, the pressure with which the roll engages the brush being varied by changing the position of said 1ongitudinally movable means on the links.

2. A brush washer comprising a supporting frame, a rotary brush carried thereby, a scrubbing roll for cooperation therewith, links at each end of the scrubbing roll pivotally connected with said frame for-movably supporting the scrubbing roll, springs cooperating with the links for yieldably holding the roll against the brush, and means carried by the links for varying-the effective action of the sprlngs- 3.

V a link pivotally suspended from the'frame at each end of the brush, a roller carried by said links, each of said linkshaving a notched portion'thereoma tensioning memberslidably carried on the notched portion of eachlink and adapted to cooperate with the notches therein, and springs connecting said tensioning members with the frame, movement of saidtensioning members on the links being utilized to vary the efiective strength of said springs.

4. A brush washer comprising a frame, a rotary brush carried thereby, a link pivotally suspended from said frame at each end of the brush, a scrubbing roller carried by thelower ends. of thelinks, and springs secured to theframe adjustably connected with said links intermediate the pivots therefor and the roller. 1
